Brand Reviews
Good protection for the price
Bought this tomzn circuit breaker for my workshop last month. Installation was pretty easy, fits standart din rail no problem. Works as expected – trips when it should and resets fine. Build quality seems decent for the money, nothing fancy but does the job.
Had one power surge and it protected my equipment well. The switching action feels solid, not cheap or flimsy. Only minor complaint is the labeling could be bit clearer but thats not a big deal.
Overall happy with purchase, good value circuit breaker that actually works. Would buy again if needed more for other projects.
Good choice
Good choice. I recommend.
